The average speed of the family during their walk will be 1.4 km per hour.
<h3>What is the average speed?</h3>
The overall distance the object covers in a given amount of time is its average speed. A scalar value represents the average speed. Its unit is a meter per second or Km per hour.
Given that over a 1.35-hour period of time, a family walk 0.75 km, stop to talk to the neighbor, and then walk another 1.15 km before reaching their destination.
The average speed will be calculated as:-
Average speed = Total distance / Total time
Average speed = ( 1.15 + 0.75 ) / 1.25
Average speed = 1.4 km per hour.
Therefore, the average speed of the family during their walk will be 1.4 km per hour.

Since the angles sum of △ is 180°,here's the equation:
60°+65°+(8x+7)=180°
8x+7=180°-60°-65°
8x=55-7
x=48/8
x=6
Thus,the answer is x=6
